The bridge manager checks the soundness of their bridges and decides the necessity of repair. On the other hand, early repairs can be difficult due to lack of budget and engineers. In response to this situation, it is thought that efficient maintenance will be possible if the quantitative data to assist the results of the inspection can be obtained and used for the necessity and prioritization of repair. Therefore, we focused on "deflection" and demonstrated several measurement techniques. As a result, it was shown that it is possible to measure properly by selecting method.
